Protection from ElectroMagnetic weapons - Part 4

Fourth part of the article would tell you more about making a Mu-Metal helmet !

Even finding a good place which sell Mu-Metal to people, not companies, was a problem.
I doubt there is a place which sells Mu-Metal helmets. And it is not difficult to make by yourself.

Please keep in mind that Mu-Metal shielding performance decreases when it is cut or bent.
It is important to make as little cutting and bending as possible, to preserve its properties.
My helmet would look like a box, because I would not bend it at all during construction.

For one helmet, you would need about 5 Mu-Metal sheets and about 0.75 square meters
(~ 8 square feet) of both camouflage fabric and strong yet light material (e.g. wooden board)

Here is a description of design: (alpha version; any improvement ideas would be welcome)

Three sides of helmet - left, right and top - could use a full-sized sheet, without cutting:
left and right sides - 8" height and 10.5" length; top side - 8" width and 10.5" length
Rear side of helmet would have 8" width and 8" length (would cut 2.5" for seams)
Front side would be 8" width and 4" height - to cover the forehead, but not to cover the eyes.
That are the approximate sizes, measure and find out which sizes would be best for your head :)

Seams should be as small as possible, but you cannot get rid of seams completely.
I am going to use one-two sheets for stripes of mu-metal, to cover seams with them.
Each stripe would be 0.75 - 1 inch in width, I have not decided about it yet

Mu-metal sheet is very thin - 0.1 mm (0.004 inch). It is easily bended and deformed
(during the testing, magnets left some small traces on the sheets, just by their movement)
We need to strengthen mu-metal with some material.

Sheets have an adhesive layer, so for each part we take a plate of strong yet light material,
(e.g. wooden board) which has the same size as Mu-metal part, and stick them together!
Exactly the same size, or little bigger - not smaller - because Mu-metal parts are thin and sharp,
and if the wooden board would be smaller they could tear the camouflage fabric that we are going to use later.

Mu-Metal is very shiny and reflective, and wooden board is not comfortable to wear.
Need to cover all "Mu-Metal + wooden board" parts with thick camouflage fabric,
from two sides: it would be comfortable inside, and insensible outside.
Fabric should sit tight, to avoid the enlargement of the seams - but not too tight,
because you would need to sew all the mu-metal parts together.

Now you have several "Mu-Metal + wooden board +
camouflage fabric" parts: big parts for sides of helmet,
and small parts for seams.

Assemble in the following way: sew a helmet "box"
from big parts, and then sew the seam covers,
the way as shown on the picture (view from top) ----->
It is better to make it so "Mu-metal" side of parts
faces the outside, and "wooden board" side of parts
faces the inside of helmet.

Mu-Metal could be used not only for defensive, but also for offensive purposes:
in case EM weapon is meant to be a portable weapon, the attacker should be protected
from the negative influence of his own weapon (Mu-Metal could cover the back side
of parabolic antenna of EM weapon) Also, it could be interesting for you to know that,
if EM weapon frequency is set up properly, it would be powerful against reptilians!

As soon as I will construct my own helmet, I promise to update and bump this thread

P.S. Send any related questions to private messages, I would be more than happy to answer
